Riom
commune in Puy-de-Dôme, France

Riom (French pronunciation: [ʁjɔ̃] ; Auvergnat: Riam) is a commune in the Puy-de-Dôme department in Auvergne in central France. It is a sub-prefecture of the department.
History
Until the French Revolution, Riom was the capital of the province of Auvergne, and the seat of the dukes of Auvergne. The city was of Gaulish origin, the Roman Ricomagus. In the intensely feudalized Auvergne of the 10th century, the town grew up around the collegiate Church of Saint Amabilis (Saint Amable), the local saint, who was the object of pilgrimages. In the 14th century the city benefitted from the patronage of Jean, duc de Berry, who rebuilt the Ducal Palace and the Saint-Chapelle. In 1531, Riom and Auvergne reverted to the Crown of France.
In 1942, Riom was the site of the Vichy government's abortive war-guilt trials, called Riom Trials.

Why this record matters

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 30, 2026. The linked authority identifier is Q207575. VIAF identifies the subject as 151276722. The Library of Congress control number is n81022945.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
